Dumping using limited system address space

摘要

Method and apparatus for reading the internal address space of an adapter in a system during a dump are described. The adapter includes a control port and a data port used as channels for exchanging control messages and dump data between the adapter and the system. The system starts the dump by sending to the data port a specification of a block of the adapter's internal address space. In response, the adapter sends dump data portions to a system buffer via the data port.
